Anest Iwata Racing introduces the latest chrome-like painting technology to the Toyota Lexus participating in Super GT300.

The indium mirror coating system is a dedicated multilayer coating process developed to achieve a high-reflectivity mirror film primarily composed of indium. The process consists of 3 coats and 3 bakes, where each layer undergoes application, drying, and heat curing (baking) to form a coating with excellent adhesion, heat resistance, and optical performance. ■ Baking Conditions (Reference Values) ProcessTemperatureTimePurpose 1st Bake (after primer): 80–100 ℃10–15 minutesSolvent evaporation and mild curing of the base layer 2nd Bake (after intermediate coat): 120–150 ℃15–20 minutesStrengthening adhesion of the intermediate layer and improving smoothness 3rd Bake (after top coat): 150–180 ℃20–30 minutesComplete curing of the final film and stabilization of mirror finish *Conditions can be adjusted based on heating methods (hot air circulation / infrared / gas type, etc.) and work material. ■ Environmental Management Requirements (Recommended) Cleanliness: Class 10,000 (ISO 7) or better Temperature: 22–26 ℃ Relative Humidity: 45–60 % Static Electricity Measures: Recommended installation of conductive flooring and ionizers *For more details, please refer to the materials.

What is an indium mirror coating system?

The indium mirror coating system is a dedicated multilayer coating process developed to achieve a high-reflectivity mirror film primarily composed of indium. The process consists of 3 coats and 3 bakes, where each layer undergoes application → drying → heat curing (bake) to form a coating with excellent adhesion, heat resistance, and optical performance. ■ Bake Conditions (Reference Values) ProcessTemperatureTimePurpose 1st Bake (after primer): 80–100 ℃10–15 minutesSolvent evaporation and mild curing of the base layer 2nd Bake (after intermediate coat): 120–150 ℃15–20 minutesStrengthening adhesion of the intermediate layer and improving smoothness 3rd Bake (after top coat): 150–180 ℃20–30 minutesComplete curing of the final film and stabilization of mirror finish *Conditions can be adjusted according to the heating method (hot air circulation / infrared / gas type, etc.) and work material. ■ Environmental Management Requirements (Recommended) Cleanliness: Class 10,000 (ISO 7) or better Temperature: 22–26 ℃ Relative Humidity: 45–60 % Static Electricity Measures: Conductive flooring and ionizer installation recommended *For more details, please refer to the materials.
